Abstract: 1,099,055. Making dynamo-electric machines; electromagnetic forming. GENERAL ELECTRIC CO. Nov. 30, 1965 [Nov. 30, 1964], No. 50844/65. Headings B3A and B3Q. In a method of placing an electrical conductor in an accommodating structure, the conductor is first arranged exteriorally of the structure so as to be movable along a confined path into the structure and then a current surge of preselected magnitude is caused to flow in the conductor to develop forces which act on the conductor to move it along the confined path and effect the placement. The coils 30, 30a, 30b of a single coil group of a distributed winding are wound in slots 137, 138, 141-144 formed in a member 145 of a holder 136 which are aligned with the slots 33, 34, 123-126 of a stator casing. A short-circuited winding 148 is carried by the member 145 and includes side sections in channels 151-156 which are joined together by sections 157, 158. The coils are connected to an energy surge supply 60 which when actuated, passes an electrical impulse therethrough. The interaction of the resulting magnetic fields set up in the coil group, the stator casing and the winding 148 causes the coil group to be ejected from the member 145 and pass into the slots 33, 34, 123- 126 and the end turns are forced back against the end faces of the stator casing. The holder 136 and the stator case may be indexed relative to one another so as to be in the correct angular position to develop the next coil group. In a modification the member 145 may be provided with two slots only and each coil of a group is positioned separately by members having slots spaced apart to match the stator case slot spacing. In a further modification an annular holder 173 is provided and an armature 172 is located therein. Convolutions 180, 180a are located in slots 176, 177 and connected to an energy surge supply 60, which, when actuated, ejects the coils into slots in the armature.

Abstract: 1,028,509. Steam generators operable at subcritical and supercritical pressures. COMBUSTION ENGINEERING Inc. Dec. 14, 1964 [Dec. 23, 1963], No. 50892/64. Heading F4A. A vapour generator is adapted to be operated as a combined circulation or once through forced flow generator at supercritical pressure and alternatively as a controlled or natural circulation generator at subcritical pressure. In the embodiment shown, under supercritical operating conditions at high load, feedwater from condenser 30 is delivered by feed pump 33 into economizer 12a to pass into steam and water drum 14a, which in this case acts only as a mixing vessel, to mingle with a small recirculated quantity of a working medium from furnace radiant tubes 18a returned through conduit 26a. From the steam and water drum 14a the medium flows through the furnace tubes 18a under the action of recirculating pump 16a, after which the small recirculated portion passes back to the steam and water drum 14a via conduit 26a, while the remaining through flow quantity passes through open valve 34 in conduit 19a to the superheater 21a and turbine generators 36. Under these conditions valve 35 in conduit 38a is kept closed to prevent medium flow from steam and water drum 14a direct to superheater 21a. Under subcritical operating conditions the generator acts a controlled circulation steam generator, valve 34 being shut and valve 35 opened, so that feed water from economizer 12a passes into the steam and water drum 14a, the water from the drum 14a being circulated by pump 16a through evaporator tubes 18a, the resultant steam/water mixture all passing via line 26a back to the steam and water drum 14a. The separated steam then passes via line 28a to the superheater 21a whilst the water mixes with the incoming feed water to be recirculated through the evaporator tubes 18a. In the embodiment of Fig. 3 (not shown), a valve is included in the line from the furnace tubes outlet to the steam and water drum which valve is kept closed during supercritical pressure operation to give a forced-flow once through circulation. Also no recirculating pump is included in the circuitry so that during subcritical pressure operation a natural circulation of the steam/water mixture occurs. A single three-way valve (Fig. 1, not shown), may replace the combinations of valves used in the preceding embodiments.

An alarm mechanism for a timepiece, particularly for sounding an alarm automatically every 24 hours in a timepiece adapted to run for a number of days, comprises a lever 30 co-operating with a cam 35 driven by the timepiece movement, a toothed wheel 4 which is rotatable when released by a locking member 9 to actuate an alarm sounding hammer (not shown), and a member 20, for transmitting motion from the lever 30 to the locking member 9, and which may be set in at least two rest positions, in one of which the member 20 urges the locking member 9 into the alarm releasing position upon a single actuation of the member 20 by the lever 30, and in another position is urged into or into a position upon actuation of the lever 30. The locking member 9 is rigid with a pivoted shaft 10 having fixed thereto an arm 12 having an abutment engaged by a spring 15 to urge a hooked end of the member 9 into a gap between studs 8 on the toothed wheel 4. A hooked end 17 on the arm 12 engages between teeth on the member 20, which is formed as a sector gear rigid with a pivot shaft 21 also rigid with an arcuate arm 22 havings digits 1, 2, 3 on its upper surface. When the end 17 is engaged between the sector teeth 18, 19 a blank portion of the arm 22 is visible through a dial window 24, whilst with the end 17 engaged between a successive pair of teeth 19, 25, 26, and 27 a digit 1, 2, or 3 will be visible. The opposite end of the spring 15 engages an abutment 31 on a face of an arm 30 having a further arm 36 engaged by the timing cam 35. At regular intervals, e.g. of 24 hours, the cam 35 causes the lever 28 to pivot clockwise, and, if the arm 22 is set so that a blank is visible through the window 24, a spur 32 on the arm 30 then abuts against the sector tooth 19 and pivots the sector 20 counterclockwise, the tooth 18 thereby urging the arm 12 clockwise to disengage the member 9 from the studs 8 to allow the alarm sounding mechanism to operate. If, however, the sector 20 and the arm 22 rigid therewith are set manually, by actuation of a lever 37, so that either of the digits 1, 2 or 3 is visible through the window 24, the alarm mechanism is not operated when the cam 35 actuates the lever 28 since none of the teeth 19, 25, 26 and 27 is of sufficient dimensions for turning the cam 12 clockwise, such actuation of the lever 28 merely causing the hook 17 to engage in the vent adjacent gap between the teeth of the sector 20 and the blank or vent; lower digit to be displayed through the window 24.
